Energy Conservation Program: Energy Conservation Standards for Metal Halide Lamp Fixtures

What it does

The Energy Policy and Conservation Act, as amended ("EPCA"), prescribes energy conservation standards for various consumer products and certain commercial and industrial equipment, including metal halide lamp fixtures ("MHLFs"). EPCA also requires the U.S. Department of Energy ("DOE") to periodically review its existing standards to determine whether more-stringent standards would be technologically feasible and economically justified and would result in significant energy savings. In this final determination, DOE has determined that more-stringent energy conservation standards for MHLFs would not be cost effective and, therefore, DOE does not need to amend its energy conservation standards for MHLFs.
